[0020] Wherein, the preparation method of the silver-copper alloy material sheet includes: melting Ag, Pt, Cu and Mg raw materials through a ZGJL0.01-40-4 type vacuum medium frequency induction furnace in an atmospheric environment to obtain an alloy ingot, and using the alloy ingot to After grinding with sandpaper, it is rolled on a rolling mill, and after multi-pass rolling and intermediate recrystallization annealing, it is finally rolled into a thin plate with a thickness of 0.3~0.4mm;
[0021] The annealing at N 2 Under protection, the annealing temperature is 850~1000℃, the holding time is 2~3 h, and the thickness of the alloy sheet is reduced by 35~40% every time an annealing is performed.
[0022] Wherein, the internal oxidation reaction includes: cutting the silver-copper alloy material thin plate into an alloy round thin slice, and cutting the thin slice into an alloy with O 2 The AgPtCuOMgO alloy material is obtained by performing an internal oxidation reaction in ...
